Later that day, Esther takes recordings from a neuron that is receiving inputs from an adjacent neuron. She exclaims to her colleague Joe, "The cell is hyperpolarized." What did Esther record from this postsynaptic neuron?

Question

Quizplus · Accepted Answer

Hyperpolarization of a neuron makes it more negative than its resting membrane potential, which is typically achieved through an inhibitory postsynaptic potential (IPSP). This process often involves the influx of chloride ions (Cl-) or the efflux of potassium ions (K+), making the inside of the neuron more negative and thus less likely to fire an action potential.
